Summary of the four experiments conducted in this study, including genotypes used, salinity treatments, dates of sowing and start and termination of salt stress treatments. DAS: Days after sowing; Control: non-stressed conditions; T1, T2, T3 Treatments with approximately 20, 55 and 90 mM of NaCl applied to maintain solution electrical conductivities equivalent to 4, 8 and 12 dS m−1, respectively.
